Well it didn't work for me as I plan'd. Bought 5,000 crystal's and went from 3 talent's to 30. Didn't get any extra talent's for using this "bug". First run it went from 3 talent's to 12 and second run from 12 to 30 talent's. Both run's it used exactly the same amount of crystal's when you buy talent's manually 1 by 1. On logbook I have more abilitys made than the real number is, just as maxtor said above.
Might be my slow connection or it really don't work, who know's :P 24mb/2mb my connection speed atm.
